Verdict
The clearest difference is ads: TommaTech at none against Yarn Unit Converter's shown. TommaTech also leads on iOS requirement (11.0 vs 17.0). Yarn Unit Converter's advantage is update cadence (every 2 days vs every 6 weeks). On price, in-app purchases and device support there is nothing between them.
